That works, but only if the layer of cones isn't too deep.
Think of it this way, if you have layers of cones that are only 1 or two cones deep, the air will probably prefer to take the zig-zag path instead of passing through the cones. This is fine since the air can contact the cones on the top and bottom.
But now let's say you have a bed that is 6 inches deep. Well the cones on the top and bottom will dry, but the stuff in the middle won't see any airflow. No airflow means it can't give up its moisture.
